On a long July afternoon in 1966, in north-west London, England’s footballers won the World Cup. By the time they beat West Germany, after extra time, with the help of a dubious goal, it was too late for the early editions of the Sunday papers. Only on the Monday was Fleet Street able to register the moment in its full glory. The Mirror, then the most popular daily ever published in Britain, with sales of 5m, knew a piece of history when it saw one. Its front-page splash proudly announced: A BOUNCING BABY GIRL FOR PRINCESS ALEX. Winning the World Cup was not as big as the birth of Marina Ogilvy, the Queen’s first cousin once removed.
The Sun didn’t lead with the football either, preferring a story about a pay squeeze; for weeks there had been a sterling crisis, and the prime minister, Harold Wilson, had loomed far larger than any footballer. Even the two papers’ sports pages, which in those days were tucked inside, went less than crazy. The Mirror had two pages reflecting on the final, the Sun a little less…
Forty years later, the World Cup was held in Germany. The England team had known only frustration in the meantime, yet they somehow loomed much larger. Every match they played was a front-page lead for both the Mirror and the Sun, and the fever had spread. The Times ran a 16-page World Cup supplement every day for three weeks…
The 2006 World Cup generated thousands of hours of television time, countless phone-ins and fan forums, endless blogs and eight hit records. It’s not just football: something similar happened in rugby with the 2003 World Cup and in cricket with the 2005 Ashes. And it’s not just Britain: each World Cup or Olympics makes more noise around the world than the last. American sport, in its different way, self-contained and tightly regulated, is getting bigger too: the television audience for the 2010 Super Bowl, 116m according to Nielsen, was the biggest ever recorded in America for any programme. With another World Cup starting on June 11th, half the nations of Europe have been strafed with giant images of the Portuguese footballer Cristiano Ronaldo in Armani Y-fronts, muscles rippling like a Greek god. Which raises the question: how did sport get so big? Whodunnit, and where, and when, and why?
